Asking for a manga

I was searching for this manga for a while
I read the first chapters on mangago, it's an ongoing manga and I remember that the uke was in a relationship with a senpai and someone saw them kissing on the library that one who saw him (who is the seme of the manga) asked him to hang out in exchange of not spreading what he saw
After that the uke realize that his senpai was playing with his feelings
Can you help me with it's name?
